The objectives of this study include: (1) analysis of Chamaecyparis
lawsoniana, C. taiwanensis, and C. formosensis forests including
the structure, composition, and dynamics of plant communities and
their environmental relationships; and (2) comparison of the temperate
Chamaecyparis forests of Taiwan and the Pacific Northwest with emphasis
on structural and successional...
Patterns of settlement of larvae and population dynamics
of juveniles are poorly known for coral reef fishes. During
1987 to 1989, I studied these phenomena in the domino
damselfish (Dascyllus albisella), a species endemic to the
Hawaiian Islands. Larvae settle onto branching coral heads
as new recruits (10-15 mm in...
Importance of tenure structures is often ignored in agricultural
development planning in India. Emphasis instead is commonly
placed on agro-techniques for increasing productivity to meet the
growing needs of food supply. To evaluate the affects of institutionalized
tenure structure on agricultural efficiency, two pairs of contiguous
districts from Madhya Pradesh,...
To determine if the distribution and frequency of dicarboximide resistance in the Botrytis population in vineyards in western Oregon is rapidly changing or remaining relatively stable. 2. To determine the relationship between fungicide use and the frequency of dicarboximide-resistant strains of Botrytis cinerea in grape, raspberry, snap bean, and strawberry...
This thesis explores the relationship between crime, transportation network connectivity, and engineered facilities built to increase walkability through a case study of twenty-five sites within the city of Spokane, Washington. Using data spanning between 2008 and 2010, the author developed a GIS model representing conditions of the built environment, social...
By examining the combined written, ethnographic and physical evidence of a surviving
steam-powered sawmill in the Douglas-fir region of the Pacific Northwest, this thesis
seeks to supply new insights into the operation and adaptability of antiquated machinery
during a period of rapid social and technological change and to develop a...
Due to its frequent use in agriculture and its frequent detection in surface water,
atrazine was chosen as a model compound to study the treatment capability of a surface flow wetland used to remediate irrigation runoff at a container nursery near Portland, Oregon. Further evaluation of treatment of atrazine was...
The objective of this study was to compare the effects on eating behavior,
lipids, lipoproteins, lipid peroxidation, and glycemic control in women with type 2
diabetes of a high-monounsaturated fat diet (HM) compared to a high-carbohydrate
diet (HC).
In an outpatient feeding study, ten hypertriglyceridemic postmenopausal type
2 diabetic women...
Nickel or nickel alloys are common materials used in under bump metallization (UBM) in flip chip technology. Nickel is used because of its slow reaction rate with tin-based solder at
elevated temperatures. However, nickel is ferromagnetic at room temperature, hence cannot be easily deposited with magnetron sputtering. In this study,...
The diverse lichen flora of the Pacific Northwest is being impacted by
population growth and by forest management practices. Accumulating information
about our lichen flora will improve our conservation strategies. This dissertation first
collects information to improve our understanding of how lichen communities vary
among forests of differing structure, and...
This dissertation consists of three essays on meta-analysis, benefit transfer and recreation use valuation. The first two essays were based on the sportsfishing valuation literature in the US and Canada while the third essay was based on a study
site in the Philippines and selected study sites from the US....
Competitive exclusion has been the mechanism hypothesized to account for the biological control of fire blight disease of pear and apple by the bacterium Pseudomonas fluorescens A506 (A506). Recent laboratory assays demonstrated, however, that A506 produces an antibiotic that is toxic to the fire blight pathogen, Erwinia amylovora, when cultured...
Small broomrape, a holoparasitic weed, is a relatively new weed introduction in the Pacific Northwest that has contaminated a limited number of red clover fields in Oregon. Greenhouse and field studies were conducted to evaluate small broomrape response to common crop and weed species in the Pacific Northwest. Host species...
Green technology in the United States has been on the rise over the past few decades in the United States. However, certain green technologies have been developed in the absence of design standards. Ecoroofs, which are vegetated soil masses placed on the top of a building’s roof structure, present several...
Nearly all birds communicate through sound, and there has been much study of avian populations and communities using song and other vocalizations. Owls are no exception as they defend territories, advertise for mates, and defend against threats using various vocalizations. However, due to their generally nocturnal habits, some owl species...
Green manures, soil solarization, and long rotations with crops not susceptible to Verticillium wilt are among the disease management tactics currently under investigation as alternatives to chemical fumigation of soil. The effect of a broccoli green manure on soil microsclerotial populations of three isolates of Verticillium dahliae and on Verticillium...
